![]() ![]() Some components may have multiple fuses, so make sure you check all of the fuses that are linked to the component in question. If your Avalanche 1500 has many options like a sunroof, navigation, heated seats, etc, the more fuses it has. ![]() Next you need to consult the 2002 Chevrolet Avalanche 1500 fuse box diagram to locate the blown fuse. Some Chevrolets have multiple interior fuse boxes including in the trunk - the video will show you where the interior fuse box of your 2002 Avalanche 1500 is located. If your Avalanche 1500 is experiencing electrical problems, you should always check the fuses first, because they are relatively easy to check and cheap to change. Electrical components such as your map light, radio, heated seats, high beams, power windows, headlights, fan blower, defroster, door lock, power seat, windshield wiper motor, fuel pump, horn, anti-lock brakes and rear view camera all have fuses and if they suddenly stop working, chances are you have a fuse that has blown out. If the headlights did not come ON, then you have eliminated the headlight switch as bad.Īlthough it's beyond the scope of this article to test for a short in the wiring between the headlight switch and the headlights, this result tells you that there is an open-circuit problem in circuit G (yellow wire).This video shows how to replace blown fuses in the interior 2002 Chevrolet Avalanche 1500 fuse box of your in addition to the fuse panel diagram location. If you'd like to save some bucks on the headlight switch, go to: Where To Buy The Headlight Switch And Save.ĬASE 2: The headlights DID NOT come ON. Taking the 3 results above into account, they tell you beyond a shadow of a doubt that the headlight switch is bad and needs to be replaced. In this test step, when you manually jumpered circuits C and G the headlights came ON.In TEST 1, you confirmed that the headlight switch is getting power in circuit C.So far you have verified that when you turn ON the headlights (via the headlight switch), the headlights do not come ON.This tells you that the headlight switch is bad and needs to be replaced. The result that you should see is that the headlights should come ON.ĬASE 1: The headlights came ON. I recommend that you make your own fused jumper wire to use in this section but you don't have to. The next step now is to use a fused jumper wire to and manually jumper circuit G and circuit C together.Ĭircuit G is the Yellow wire sticking out of the headlight switch connector. So far in TEST 1, you have confirmed that there's battery voltage (10 to 12 Volts DC) in circuit C (circuit C is the red wire). TEST 2: Fused Jumper Wire (Headlight Circuit) This test result also tells you that the headlight switch is not bad since without power in this circuit, it can not turn on the headlights. If your multimeter still does not register battery voltage, then this tells you that the reason that the headlights are not coming ON when is a lack of power. For this test, go to: TEST 2: Fused Jumper Wire (Headlight Circuit).ĬASE 2: The multimeter DID NOT register 12 Volts. The next step is bypass the headlight switch with a jumper wire and see if the headlights come on. ![]() This is the correct and expected test result and tells you that the circuit that controls the headlights (inside the headlamp dimmer switch does have power). Let's take a look at what your test results mean:ĬASE 1: The multimeter registered 12 Volts. Voltage should be present whether the key is in the ON position (in the ignition switch) or not. Your multimeter will register one of two things: battery voltage (12 Volts) or no voltage at all. ![]()
